Pros
The "checkfree culture' has pretty much disappeared with some small remnants still remaining. The only positive thing is the company cafeteria in Norcross has great food. Other than that, I would NOT recommend Fiserv. Some great people in place but the former COO and several other SVP's are leaving like "rats on a sinking ship."
Cons
The company cuts 5% of it's workforce and the remaining employees are worked like dogs. No recognition, no advancement opportunity, and horrible communication. Morale is at an alltime low and the turnover rate is 25% up from 18% in 2010. Fiserv has not given raises in the last three years. I was a former corporate recruiter for this company and I highly recommend that you do not dead-end your career at this place. Almost everyone I know is looking to leave this place.
